Answer:
the y-value of the vertex = 1,125
Step-by-step explanation:
The table is as shown at the attached figure.
By graphing values in an x-y plane and observe the graph.
From the illustration, locate the vertex. The vertex of the parabola is (5, 1,125). So, the y-value of the vertex of the parabola that models the data is 1,125.
See the graph between x and y.
Answer:
28 -16n
Step-by-step explanation:
Use the distributive property, then collect terms.
4 +8(-2n +3)
= 4 +8(-2n) +8(3)
= 4 -16n +24
= 28 -16n
_____
This could also be written
-16n +28
but then the leading sign would be negative. Sometimes leading minus signs get lost, so I prefer the first term to be positive.
